Pilot Navigation System developed by Maritime University of Szczecin Stefan Jankowski

Introduction Limitations when navigate at constrained water areas: Weather conditions, Visibility, Night-time, Dense traffic.

Introduction Potential users of PNS: pilots, ferries, other vessels permanently navigate at definite area.

Stationary PNS Collecting information subsystem Data processing Subsystem Visualization of navigation information Subsystem Prediction subsystem – hydrodynamic model Electronic chart (Data base) DGPS Gyro Rudders Bow thrusters Propellers Wind

Portable PNS Collecting information subsystem Data processing Subsystem Visualization of navigation information Subsystem Prediction subsystem – extrapolation model Electronic chart (Data base) Compass DGPS Manual data collection

Development PNS principles: precisely determination of vessel’s position at restricted area; suitable type and content of information; suitable form of presentation of that information

Development Tools and methods : Optimization of information in PNS; Visualization of optimal information; Creation of very specific Electronic Chart; Methods for adjusting vessels waterline; Tools for assessment and verification of satellite positioning systems.

Optimization of information The optimal set of information should enable to make a planned manoeuvre: safe; in given time; in given conditions.

Optimization of information The optimal set of information : heading; course over ground; speed over ground; distances to the berth; safe depth contour; rate of turn; cross speed.

Visualization Shore visualization

Visualization Fairway visualization

Chart – adjustment

Chart – safety contour V2 > V1 T2 > T1 Result: new safety contour displayed on the chart

Chart – prediction

Positioning subsystem The most favourable solutions: stationary PNS - positioning subsystem made up of DGPS receiver and gyrocompass (p = 1.3 m); portable PNS - positioning subsystem made up of compass GPS (p = 1.5 m).

Summary This system is not a standardized electronic chart and has following distinctive features: integration with the water area, integration with the vessel, optimal information, optimal user’s interface, predicting and supporting manoeuvring.

Summary Portable version - pilots.

Summary Stationary version – ferries

Summary – new features
